EEKeeper Creatures Not Updating.

First time using EEKeeper, been using NI in the past. So I changed my saved game character and a few NPC's and it all went ok.

Then I thought I would modify some creatures. I have a Mega Mod set up and installed with Big World Set-Up. Using the "Tactics" option. On level 3 of the Naskil Mines someone decided to put 5 nasty critters that are impossible for a level 1 party to kill. So I used EEKeeper to edit them. Ive always been able to do this with Near Infinity on the original versions of a Mega Modded Baldurs Gate.

I re-start the game, play that encounter, and nothing changed. I use EEKeeper to relook at what I changed and yep everything looks good.....but in the actual game nothing. I start a new game thinking maybe it doesnt effect saved games, I port my character directly to level 3 Nashill Mines, cntr Y kill everything and nothing. They are still the originals. Also I open the game with Near Infinity, navigate to the creatures and they show as being modified.

What is up with this? Are there creature stats in two locations with EE? I see these ones I am modifying are kept in the override folder. But shouldn't they be updating in game immediately?
